Widely considered to be the definitive of the many film versions of Charles Dickens' classic novel is this 1951 British adaptation, starring Alastair Sim (titled Scrooge in its U.K. release).
Sim plays Ebenezer Scrooge, a London miser who, despite his wealth, refuses to make charitable contributions and treats his sole employee, Bob Cratchit, as an indentured servant.
On Christmas Eve, Scrooge is visited by the ghost of his late business partner, Jacob Marley, who was as selfish as Scrooge in life and has been condemned to an eternity of wandering the Earth in shackles.
Marley informs Scrooge that he's to receive a trio of spirits that night who will take him on a journey through Christmases Past, Present, and Yet to Come. As Scrooge encounters each apparition, he is taken on a tour of his life and realizes what a wretch he is, transformed by greed from an idealistic youth into an embittered ogre.
Infused with a new, cheery outlook, Scrooge sets about earning his redemption.
